There is one timeless way of building.

It is thousands of years old, and the same

today as it has always been.The great traditional buildings of the past,the villages and tents and temples inwhich man feels at home, have alwaysbeen made by people who were very closeto the center of this way.

It is not possible to make great buildings,or great towns, beautiful places, placeswhere you feel yourself, places where youfeel alive, except by following this way.

And, as you will see, this way will leadanyone who looks for it to buildingswhich are themselves as ancient intheir form, as the trees and hills,and as our faces are.

Hybrid between design,engineering, and marketing.

No definitive formulation. Considerable uncertainty. Complex interdependencies. Incomplete, contradictory, and

changing requirements.

Stakeholders have radicallydifferent world views.

Its a project and a process. The problem is never solved.

Search is a Wicked Problem
